Troubleshooting Procedures: Notes

  1. How To Begin Troubleshooting

    When the Malfunction Indicator Lamp (MIL) has been reported on, the low fuel indicator light has been blinking, or there is a driveability problem, use the appropriate procedure below to diagnose and repair the problem.

    1. When the MIL has come on, or if the low fuel indicator light has been blinking:
      1. Connect the Honda PGM Tester or an OBD II scan tool to the 16P Data Link Connector (DLC) located near the left kick panel.
      2. Turn the ignition switch ON (II).
      3. Check the DTC and note it. Also check and note the freeze frame data.
      4. Referring to the Diagnostic Trouble Code Chart, begin troubleshooting.

      NOTE:
      • See the OBD II scan tool or Honda PGM Tester user's manuals for specific operating instructions.
      • The OBD II scan tool or Honda PGM Tester can read the Diagnostic Trouble Codes (DTC), freeze frame data, current data, and other Powertrain Control Module (PCM) data.
      • Freeze frame data indicates the engine conditions when the first malfunction, misfire or fuel trim malfunction was detected. It can be useful information when troubleshooting.
    2. When the MIL has not come on, but there is a driveability problem, refer to the Symptom Chart  .
    3. DTCs will be indicated by the blinking of the Malfunction Indicator Lamp (MIL) with the SCS service connector connected.

      Connect the SCS service connector to Service Check Connector as shown. (The 2P Service Check Connector is located under the dash on the passenger's side of the vehicle.) Turn the ignition switch ON (II).

  2. Powertrain Control Module (PCM) Reset Procedure

    Either of the following actions will reset the PCM.

    • Use the OBD II scan tool or Honda PGM Tester to clear the PCM's memory.
      NOTE: See the OBD II scan tool or Honda PGM Tester user's manuals for specific operating instructions.
    • Turn the ignition switch OFF. Remove the BACK UP (RADIO) (7.5 A) fuse from the under-hood fuse/relay box for 10 seconds.
    NOTE: Removing the BACK UP (RADIO) (7.5 A) fuse cancels the clock and the radio presets. Make note of the customer's presets so you can reset them.

  3. Final Procedure (this procedure must be done after any troubleshooting)
    1. Remove the SCS Service Connector if it is connected.
      NOTE: If the SCS service connector is connected and there are no DTCs stored in the PCM, the MIL will stay on when the ignition switch is turned ON (II).
    2. Do the PCM Reset Procedure.
    3. Turn the ignition switch OFF.

If the inspection for a particular code requires voltage or resistance checks at the PCM connectors, remove the right kick panel. Pull the carpet back to expose the PCM. Remove the ABS control unit if so equipped. Unbolt the PCM bolt. Turn the ignition switch OFF, and connect the backprobe sets and a digital multimeter as described below. Check the system according to the procedure described for the appropriate code(s) listed on the following pages.
